description:
Pull up revision 1.6 (requested by thorpej in ticket #635):
   o Add -march=armv5, -march=armv5t, -march=armv5te, which are
     internally treated like -march=armv4t, but which generate
     __ARM_ARCH_5__, __ARM_ARCH_5T__, and __ARM_ARCH_5TE__
     defines, respectively.
   o Add -mcpu=xscale, which is internally treated like
     -mcpu=strongarm, but which generates __ARM_ARCH_5TE__ and
     __XSCALE__ defines.

  These command-line options and definitions are consistent
  with gcc 3.x, and allow NetBSD Makefiles to use them in a
  forward-compatible way, and also give hand-tuned source
  code (e.g. assembly) a chance of tuning for XScale.
